Can somebody explain to me what 'broader' and 'narrower', unqualified,
mean now?
Given that the whole semantics of SKOS are now completely undefined,
and that the core guide is going to have to be completely rewritten,
what do these terms mean.
We know that they can't be *any* kind of orderings.
We know that they can't be associative relationships, because
otherwise they'd just be called relationships. We know that the
language used in the SKOS Core Guide has previously been taken from
and aligned with Z39.19 et al, but that this is no longer acceptable.
Just calling an associative relationship hierarchical does not make it
so. The LC made tried that twenty years ago. Mary Dykstra(1988)
explained the problems with this approach (if you haven't read this
article, it's very helpful background for this discussion).
I I have no problem with SKOS being used to represent false claims;
I'm working with the LCSH, which, being of Congress, is riddled with
the things. Redefining an existing concept so as to make the false
claims become true brings in to question the whole exercise. 'Sorry
if I'm sounding like a broken record on this, but the broadening that
I'm most afraid of is the whole thing going pear-shaped.
If having a transitive broader is too problematic, can we at least
remove unqualified broader and narrower completely?
